When the air conditioner is not going to be used for a long time.

CAUTION

Operation Tips

Helpful information

The air filters and your electiric bill.

If the air filters become clogged with dust, the

cooling capacity will drop, and 6% of the electricity

used to operate the air conditioner will be wasted.

When it is not going to be used for

a long time.

When the air conditioner is to

be used again.

Operate the air conditioner on Air

circulation mode for 2 to 3 hours.

• This will dry out the internal parts.

Turn off the circuit breaker.

Turn off the circuit breaker when the air conditioner

is not going to be used for a long time.

Dirt may collect and may cause a fire.

■ Check that the air inlet and outlet of the

indoor/outdoor unit are not blocked.

Do not overcool the room.

This is not good for the health

and wastes electricity.

Keep blinds or curtains

closed.

Do not let direct sunshine

enter the room when the air

conditioner is in operation.

Make sure that the doors

and windows are shut tight.

Avoid opening doors and

windows as much as possible

to keep the cool air in the

room.

Clean the air filter regularly.

Blockages in the air filter

reduce the airflow and lower

cooling and dehumidifying

effects. Clean at least once

every two weeks.

Ventilate the room

occasionally.

Since windows are kept

closed, it is a good idea to

open them and ventilate the

room now and then.
